2 Claims. (Cl. 20-71) This invention relates to window guard structures, and more particularly to an improved movable guard structure for windows of the double-hung type.

A main object of the invention is to provide a novel and improved guard structure for windows of the doublehung type, said guard structure involving relatively simple. components, being easy to install, and being effective to render the associated window proof against intruders when the window is in an otherwise open condition, as well as to protect occupants from any danger of falling out of the window.

A further object of the invention is to provide an improved guard structure for a window of the doublehung type, said guard structure involving inexpensive components, being relatively. inconspicuous in appearance, being completely hidden when the window on which it is mounted is closed, and providing positive protection against the entry of intruders when the window is open.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 11 is an enlarged horizontal cross sectional detail view taken on the line 11-11 of Figure 10.

Figure 12 is a fragmentary vertical cross sectional view, similar to Figure 10, and showing a modified form of guide sleeve element which may be employed in the window sill to guide a vertical guard bar, in a window guard structure according to this invention.

Figure 13 is an enlarged vertical cross sectional view taken through the rod guide sleeve structure of Figure 12.

Referring to the drawings, and more particularly to Figures 1 and 2, 11 designates a building wall in which is provided a window frame 12 containing a double-hung window of generally conventional construction, the frame including the respective side members 13 and 14, the top member 15 connecting the top ends of said side members, and the horizontal sill 16 connecting the lower ends of the side members. Slidably mounted in the frame in the usual manner are respective sash members, the outer sash member being shown at 17.

Rigidly secured to the horizontal lower element 18 of the outer sash member 17 are a plurality of spaced, depending parallel bars 19, said parallel bars extending slidably through respective apertures 20 provided in the sill member 16 and through similar apertures provided in the subjacent horizontal stud member 21. The lower ends of the bars 19 are provided with transversely extending abutment elements, such as the horizontal transverse arms 23, preventing the upward removal of the bars 19 from the stud 21.

As shown in Figure 2, the top ends of the bars 19 may be rigidly secured to a transversely extending, relatively flat bar 24 which is received in a groove 25 pro- -vided in the bottom edge of the bottom sash element 18, the bar 24 being secured in the groove 25 by a plurality of fastener screws 26 engaged through the bottom sash element 18, as shown.

Designated at 27 is a horizontal bar member which is formed with spaced apertures through which the respective vertical bars 19 are slidably received, the horizontal bar member 27 extending transversely across the space between the window frame side members 13 and 14-. A pair of vertical bars 19 at opposite sides of the window are formed at their intermediate: portions with stop lug elements 28, 23 projecting on opposite sides thereof, supporting the bar 27 in a position substantially midway between the bottom element 18 of the window sash 17 and the sill 16 when the window sash 17 is in its fully raised position, as shown in Figure: 1.

A vertical bar 19' located adjacent to the window frame side element 13 extends slidably into a vertical recess,

29 formed in the adjacent side portion of the window sash 17, whereby the sash 17 may move freely with respect to the bar 19. The bar 19 is formed with outwardly projecting lugs 31, 31 at the intermediate portion thereof, said lugs overlying the end portion of horizontal bar 27, and holding the horizontal bar 27 down so that it is urged into contact with the respective pairs of supporting lugs 28, 28, whereby the bar 27 is urged toward a horizontal position resting on the lugs 28.

As will be readily apparent, when the sash 17 is lowered to its closed position, the vertical bars 19' and the horizontal bar 27 are substantially hidden from view, whereby the window presents a completely normal appearance. When the sash 17 is raised to its open position, for example, to the fully raised position thereof shown in Figure 1, the vertical bars 19 are elevated to positions covering the open lower portion of the window, thus protecting the building against the entry of intruders, and also serving to protect individuals, such as children from falling'out of the window.

In the modified form of the window guard structure of Figure 3, a horizontal plate member 24- is secured to the bottom edge of the window sash 17', the being suitably recessed to receive said plate member 24, the plate member having vertical lugs 32, 32 at its opposite ends received in recesses provided therefor in the lower end portions of the respective side elements of the Window sash, the plate member 24 and the lugs 32 being secured to the sash by fastening screws 33, as shown'in Figure 3. The top ends of the bars 19 are rigidly secured to the plate member 24.

In the modified form of the invention shown in Figure 4, the bottom plate member, similar to the plate member 24" of Figure 3, and designated in Figure 4 at 34, is formed with an aperture 35 to receive the vertically slidable side bar 19. In the embodiment of Figure 3, said side bar 19 is omitted. In the form of the invention shown in Figure 6, a bar 34 is secured in a recess provided therefor in the bottom edge of the sash 17, the bar being formed at one end thereof with the fork 36 defining the spaced arms 37, 37. The space between the arms 37, 37 is aligned with the recess 29 in the side portion of the sash in which the vertically movable bar 19 is receivable. As shown in Figure 7, said bar 19 extends between the arms 37, 37 of the fork element 36, allowing the upper portion of the bar 19' to freely slide in the recess 29.

Figure 8 illustrates a modified form of bottom end structure which may be provided on the respective vertical bars 19, for example, a pair of pivoted toggle elements 38 and 39, said toggle elements being provided with pivot lugs engaging on opposite sides of the bottom end of the bar 19 in overlapping relationship, and connected to the bar 19 by a transverse pivot pin 40. The arms 38 and 39 may be initially rotated to positions adjacent the opposite side surfaces of the bar 19, allowing the bar to be passed through the aperture 20 provided therefor in the window sill 16, and the corresponding aperture provided therefor in the horizontal stud element 21, after which, the arms 39 and 38 drop to their horizontal positions, shown in Figure 8, preventing the bar 19 from thereafter being lifted through stud 21 and sill 16. As shown in Figure 8, the arm 38 may be provided with an abutment shoulder 41 against which a similar abutment shoulder on arm 39 is engageable, to limit relative rotation of the arms 38 and 39 downwardly beyond the positions thereof shown in Figure 8.

Figure 9 illustrates a further toggle bolt arrangement comprising a guard element 42 pivoted at its intermediate portion in a slot 43 formed in the lower end of the vertical bar 19, the rod element 42 being fastened to said lower end by a transverse pivot pin 44. The rod element 42 may be rotated to a vertical position wherein its upper portion is received in the slot 43, When the rod is inserted through the associated aperture 20 in sill 16 and the corresponding aperture of the subjacent stud 21, after which the rod element 42 rotates to a horizontal position, as shown in Figure 9, preventing upward removal of bar 19 from stud 21 and sill 1.6.

As shown in Figures and 11, the sill 16 may be provided 'with respective guide bushings 45 slidably receiving'the respective vertical rods 19. Each guide bushing 45 tapers downwardly in diameter, as shown in Figure 10, and is provided at its top end with the outwardly extending stop lugs 46, 46, limiting downward movement of the bushing with respect to the top surface or sill 16. The sill 16 is formed with suitable downwardly tapering recesses to receive the bushings 45, each recess being'formed with a pair of diametrically opposed intermediate recesses 47, 47 adapted to receive respec tive resilient locking pin elements 48, 48 provided on the intermediate portion of each bushing at diametrically opposite locations thereon. The resilient locking pins 48 are yieldable to allow the associated bushing to be inserted in its recess, but lockingly engage in the locking grooves 47, 47 to retain the bushing in its properly seated position. In the form of the invention illustrated in Figure 10, a headed stop screw 23 is engaged with the bottom end of the vertical rod 19, to limit upward movement of the rod 19 with respect to the sill 16. Obviously, where access to the rod 19 is not available, a toggle bolt arrangement, such as shown in Figure 8 and in Figure 9 may be employed instead of the headed bolt 23;

In the modification illustrated in Figures 12 and 13, the guide bushing, shown at 45' is formed with a slot 49 in which a locking arm 50 is pivoted, as by a pivot pin 51. The locking arm 50 is biased outwardly by a coiled spring 52 secured to the locking arm and bearing against the associated vertical rod 19. The arm 50 is lockingly engageable in a recess 53 provided in the bore in which the bushing 45 is seated.

Obviously, the arm 50 may be biased outwardly in any suitable manner, as by providing a bearing for the spring 52 in the'slot 49, rather than relying upon the bar 19 asa bearing, whereby the bushing 45' will beanchored in its aperture in sill 16 independently of the rod 19 associated with the bushing.

The guard structure above described may be employed with windows made of various different materials, such as metal, plastic, wood, or the like, and obviously, may be employed with windows other than the double-hung type.

If so desired, the auxiliary vertical bar 19 may be omitted, within the spirit of the present invention.

The guard structure of the present invention may be employed with either horizontal or vertical windows of either the double-hung or sliding sash type.

While certain specific embodiments of an improved guard structure for a double-hung window have been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
